What Is 2011 Rolex 24 Hours of Daytona

Overview

The 2011 Rolex 24 Hours of Daytona was the 49th running of the iconic endurance race, serving as the opening event of the 2011 Rolex Sports Car Series season. Held at Daytona International Speedway in Daytona Beach, Florida, the race began on January 29 and concluded on January 30, 2011, drawing teams from around the world to compete in a grueling 24-hour test of speed, strategy, and mechanical reliability.

This edition marked a significant moment in sports car racing history due to high team participation and competitive balance across multiple classes. The race featured dramatic weather changes, mechanical failures, and intense driver rotations, making it one of the most unpredictable Rolex 24s in recent memory.

• Start Date: The race officially began at 3:30 PM Eastern Time on January 29, 2011, under partly cloudy skies with mild temperatures.
• Winner: The No. 01 Chip Ganassi Racing Riley-Ford Daytona Prototype completed 770 laps, the highest total of any car, securing first place overall.
• Winning Drivers:Scott Pruett, Memo Rojas, João Barbosa, and Terry Borcheller shared driving duties, each averaging two-hour stints throughout the race.
• Total Entries: A field of 58 cars was divided into four classes: Daytona Prototype (DP), GT, GX, and the single-make Porsche 911 GT3 Cup in the Rolex Series Challenge.
• Weather Impact: Heavy rain in the early morning hours of January 30 caused multiple caution periods and forced teams to adapt tire and fuel strategies on the fly.

How It Works

The Rolex 24 Hours of Daytona is structured as a 24-hour endurance race where teams of drivers rotate behind the wheel to maximize track time while managing mechanical wear and fuel consumption. Each car must complete as many laps as possible over the full day-long period, with the winner determined by total laps completed.

• Daytona Prototype (DP): The top-tier class featured custom chassis with production-based engines; in 2011, Riley, Dallara, and Courtyard by Marriott were represented with Ford and BMW powertrains.
• GT Class: Included production-based sports cars like the Chevrolet Corvette C6.R and BMW M3, modified to strict FIA GT regulations for balance of performance.
• Driver Rotation: Each team used 3 to 5 drivers, with mandatory minimum drive times and maximum stint limits to ensure driver safety and fairness.
• Refueling Rules: Teams refueled approximately every 45 to 50 minutes, with pit stops also including tire changes and mechanical checks.
• Caution Periods: The race saw 11 full-course caution flags, totaling over 2 hours of yellow-flag conditions, often due to crashes or weather.
• Scoring System: Results were determined by total laps completed, with ties broken by elapsed time to finish the final lap.

Comparison at a Glance
